Ely Tea Party 0.3.4

The app now tells you when a new version is out, and on macOS updates itself.

Updates from the title bar

• At start, every 6 hours, and from Ely Tea Party → Check for Updates…, the app asks GitHub for the newest release. When one is newer, a 更新到 X.Y.Z button appears in the title bar.
• On macOS one press downloads the disk image, checks it is signed by the same Developer ID, notarized, and the version it claims, and puts it in place of the running app. The button then says 重启以完成更新; press it when you're ready to restart, so your sessions aren't cut off mid-task. Your sessions come back after the restart as usual.
• On Windows and Linux the button opens the release's page.
• This release is the last one you install by hand: 0.3.3 and earlier have no button.
